If I did get a 9800GX2 (seems like a good decision) i would probably go for like a P43 because I have heard the the nVidia boards don't OC as good as the P43/P45.
well some nvidia boards overclock and some dont. but if you want to overclock then get a p45 board. guaranteed overclock there. but to do quad sli you need a nvidia board. if i were to do quad sli i would get a 780i.
Here is the final list, can someone please check it make sure everything is good. My biggest concern is the PSU I want it to be modular, I think the one I have selected now will do fine with the 4870 and an e8400 OC, but can somone check that just to make sure?
